' l Apfiimiqn and July 2, 1888. serai No. 278,746.' or@ model.)

To all whom it may concern:

Be it known that I, DANIEL I-1UBBARD,-of Oswego, in the county ofOswegofand State of NewYork, have invented certain new anduseful'lmprovements in Stoves, of :which the' following is a full,clear, and exact description. f

My invention relates toan improvement in stoves, and has for its objectto provide a stove of simple construction which will be economical inthe consumption of fuel' and wherein the gases ordinarily permitted Sto'escape throughrthe otake-iiue-will bev con- The further obj ect of theinvention is .to provide a stove Vwhich may be readily cleaned,containingfewv parts, and not liable to disarrangement, and wherein theproducts of combustion are utilized to `Va maximum extent and a maximumdegree of radiation obtained. o.

The invention consists in the'construction and combination of theseveral parts, as will be hereinafter fully `set forth, and pointed outin the claims. i Y

Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar igures of reference indic'atecorresponding parts in all the views.

Figure 1 is a centralvertical section through the complete stove, takenon line w w of Fig. 2.H Fig. 2is a planview of the same. Fig. 3 is ahorizontal section taken on line w of Fig.r1. Fig. 4 isa horizontalsection on line y y of Fig. 1, and Fig.`5 4is a similar' section on linea a' of Fig. 1.

In carrying out the invention the stove is provided with an outer casingor jacket 10 and an inner spaced casing 11, the latter casing beingprovided with a closed bottom, an open top, and an outwardly-projectingiiange 13, integral with said top,fwhich iiange is adapted to rest uponthe upper edge of the outer casing or jacket, as best shown in Fig. 1,sustaining the said innercasing in position. At or'near the bottom ofthe stove upon one side a horizontal opening 14 is formed, the cut-awayportion of the inner andv outer cylinder surrounding this opening beingclosed in any suitable manner, thus providing a closed chamber 15,having but one outapproved manner,

let, which is located at or near the top and surrounded by a stove-pipecollar 16.

. The base 17 of the stove proper is made to rest upon the bottom of theinner cylinder 11. The grate is shown at 18. That portion of the baseforming the ash-pit is adapted to project outward through the opening 14in the casing, being provided with suitable drafts openings 20.

Thefire-pot 24 consists ofva cylinder, which 2 may or may not be lined,supported uponthe base 17 in any approved or suitable manner.

A preferablyoblong casing 25 is attached at one end to the upper end ofthe iire-pot, y the bottom of the said casing being provided with anaperture of equal diameter to that of the diameter of the said fire-pot,whereby communication between the ire-pot and the chamber 26, formed bythe said casing 25, is freely obtained. The oblong casing 25 extends theentire width of the inner cylinder 11, and

is provided upon the upper face at the end opposite to the fire-pot withupwardly-projecting walls 27, whereby another chamber 28 is obtained,which chamber is closed through the medium of a cover 29,having anaperture 30 produced therein, preferably covered with a sheet of mica31, or other transparent or translucent material, to observe the iiameas it goes down the center pipe.

Immediately over the fire-pot 24 a magazine 32, by which the saidfire-pot is supplied with fuel, is introduced. The magazine 32 maybestayed or braced at the top in any suitable or and is retained inposition within the casing 25 through the medium of -an annular flange33,which i'iange rests upon the upper surface of the aforesaid casing25.

An inlet-aperture 34 is provided in the bottom of the inner cylinder 11and the rear of the base 17, which aperture is surrounded by apreferably conical tube 35, the said tube being adapted to extend upwardthrough an aperture produced in thelower face of the casing 25, as bestshown in Fig. 1. The said tube 35, which I for convenience denominate afire-tube, is surroundedtby a second spaced tube 36. The lattertube issecured at the upper end to the bottom of the said casing 25, extendingthrough the same opening through which the fire-tube 35 is passed.-

IOO

The lower end of the said tube 36, which I denominate a hot-air tube,extends down to the bottom of the inner casing 1l in similar manner tothe fire-tube 35, as is also best illustrated in Fig. 1.

The fire-pot 24 is surrounded by a spaced jacket 38, which jacketpreferably extends from the top of the said fire-pot to about the centerof the same, and is connected with the hot-air tube 36 through themedium of a transverse pipe 39. This pipe 39 may, if found desirable,beprovided with a damper 40, having an attached rod preferably passedthrough the outer casing. A hot-air tube 41 is formed in the chamber 26through the medium of a ianged cap-plate42, the flange of which plate,

being attached to the end side, is adapted to rest upon the inner faceof the bottom of the said chamber 26 above the several tubes 35 and 36.The lire-tube 35 is preferably secured to the end surface of thecap-plate 42, and immediately over the said tube 35 an aperture 43 isproduced in the cap-plate of less diameter than the diameter of thetube, and at or near the bottom of the tube 35 a ring 44 is introduced,as will be hereinafter set forth.

The cap-plate 42 is provided with channels 45, one being located at eachend adjacent to the fire-pot, each of which channels extends a slightdistance inward over the said repot, being adapted to supply heated airto the products of combustion, as will be hereinafter set forth.

The chamber 41, formed by the cap-plate 42, I will for conveniencedesignate as a burner. Intermediate of the two channels 45 of thecap-plate the said plate is carried downward at an inclination (as bestshown in Figs. l and 3) at 46, to an engagement with the inner bottomface of the casing 25. A partition 47, having a central (preferablycircular) aperture 48, is made to bear against the walls of the casing25 and rest upon the inclined surface 46 of the burner, as is also bestillustrated in Figs. l and 3, thus reducing the`opening between thatportion of the chamber 26 over theburner and the fire-pot.

The stove is provided, with an open or essentially open cover or top 49,having a handle 50, by which the same may be readily manipulated.Ordinarily the cover 49 is provided with a slide 51, located over themagazine 32.

In operation, a fire having been built in the fire-pot, the products ofcombustion pass from said fire-pot through the aperture 48 of thepartition 47 down through the aperture 43 into the fire-pipe 35, thering 44 and the Walls of the aperture-43 preventing the products ofcombustion from coming in direct contact with the sides of the saidflue. From the ue 35 the products of combustion pass into the chamber 15andA circulate freely around the same, passing out through the aperturein the rear, surrounded by the 0E- takepipe collar 16. The cold airentering at the top or at the bottom through the space provided by theopening 14, or both, passes `up between the jacket 38and the fire-pot24,

where the said air is partially heated. From thence the air passesthrough the short pipe 39 up through the hot-air pipe 36 into the burneror chamber 41 and is delivered from said chamber through the medium ofthe channels 45 over the fire-pot, inside of the partitions 47. I-lotair thus 'being supplied to the products of combustion causes theescaping carbonic-oxide gases to take fire. The said ignited gasesthereupon pass out through the aperture 48 in the partition, asheretofore stated.

It willl be seen that fresh heated air is constantly supplied to thelire above the dame, insuring the effective combustion of any unconsumedgases. 1

I do not confine myself to the construction of theburner whereby theheated air is conveyed to the nre-pot through spaced channels, as thechannels may be dispensed with and perforations be substituted, or thechannels and perforations may be used jointly.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent-` is- 1. The combination, with the fire-pot anda horizontal casing, forming a combustionchamber, extending rearwardlyfrom theirepot and provided with an outlet, of a burner in therearward-proj ectin g part of the said chamber and provided with spacedair-channels opening over the fire-pot, and a jacket surrounding thefire-pot providedy with an air-inlet and connected with said channels,substantially as set fort-h.

2. The combination, with the fire-pot and a horizontal casing, forming acombustionchamber, extending rearwardly from the firepot and having anoutlet, of the horizontal burner having spaced air-channels opening overthe fire-pot, an apertured partition dividing the combustion-chamberabove the burner and in rear of the fire-pot, and through which aperturethe products of combustion pass to the outlet, andv the jacketsurrounding the fire-pot, open at its lower end' to receive the air andconnected with the burner to supply its channels with heated air,substantially as set forth.

3. In a stove, the combination, with an inner and an outer cylinder, afirepot within the inner cylinder, an oblong casing supported above saidfire-pot, extending horizontally beyond the same and forming thecombustionchamber, and a burner horizontally supported within the saidcombustion-chamber at one side of the fire-pot, provided withconductingchannels extending into the fire-pot and an aperture in theupper face, of an apertured partition dividing the combustion-chamberinto two compartments, a jacket surrounding the-irepot,.an air-tubeconnected with said jacket and burner, a tire-tube provided with aring'surrounding the opening in the burner and passing downward withinthe air-tubeto a connection with the space intervening the IOO IIO

' inner andouter casing, and means, substantiaiiy as shown anddescribed, for introducing air betweenthe jacket and the burner, as andfor the purpose specified, )vhereby hot air is supplied to the productsof combustion Within the fire-pot and the escaping carbonicoxide gas isconsumed, as set forth.

4. In a stove constructed substantially as herein shown and described;the combination, with a iire-pot, and a casing supported above saidfire-pot, extending beyond one side of the same and forming thecombustion-chamber, ofv a burner supported in thesaid combustionchamber,having tubular channels projected from the ends adjacent to the fire-potand leading into the'iire-pot, and a centrallyapertured partitionresting upon said burner` and the Walls of the casing, dividing thechamber yinto two sections, andineans for supplying air to said burnerand conducting the products of combustion from the fire-pot,substantially as and for the purpose specified.
